and high‐fidelity PEG‐amine with carbamate linkage was obtained, as seen from the clean MALDI‐TOF MS pattern. The carbamate strategy was further applied to the synthesis of high‐fidelity multi‐functionalized PEG with varying reactive groups. Compared to with an ester linkage, amphiphilic PEG‐PS block copolymers bearing carbamate junction linkage exhibits preferential self‐assembly tendency into vesicles

A new procedure that employs a one-pot, oxidative Hofmann rearrangement to incorporate a urea linkage into peptide backbones is detailed herein. This methodology was used to replace the scissile peptide bonds of [Leu(5)]enkephalin and a hexapeptide HIV-1 protease substrate. The [Leu(5)]enkephalin analogue was found to inhibit cleavage of hippurylhistidylleucine (HHL) by porcine kidney angiotensin-converting enzyme (PK-ACE) with a 0.88 mM IC50 value, comparable to the Michaelis constant of [Leu(5)]enkephalin with the same enzyme. The HIV-1 protease substrate analogue was shown to inhibit HIV-1 protease with an IC50 = 34muM. (C) 2004 Elsevier Ltd. All rights reserved.
